Machine Learning Model for Nd
Article in Materials (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We demonstrate an efficient machine learning (ML) model for the prediction of magnetic property changes in Nd2Fe14B-based permanent magnets given a large range of different impurity elements. We show that relatively simple models can be sufficient to capture complex changes in the saturation magnetization Ms and the magnetocrystalline anisotropy constant K1. As the necessity for recycling the raw material of permanent magnets increases, the variety of impure chemicals and their concentrations increase as well. Some chemical elements with antiferromagnetic or complex magnetic ground states like Cr, Mn and Sm pose difficulties in the training of an ML model that can be effectively mitigated by feature engineering. This enables us to create a single model capable of describing more than twenty substitutional elements in a wide range of concentrations.
